摘要：
Absorption depletion indicators for anesthetic gas administration systems which, in a closed or semi-closed system of anesthetic gas administration comprising a canister held absorbent for carbon dioxide, the improvement is characterized in that an indicator is provided for the canister for determining when the carbon dioxide absorbent is exhausted, the indicator is in the form of a wax temperature indicator calibrated permanently to change colour at a temperature of the absorbent indicative of exhaustion of the absorbent due to carbon dioxide absorption.
